RADiANT STOVE.

SPECIFICATION forming part of Letters Patent No. 739,726, datedSeptember 22, 1903. Application filed May 18; 1903. Serial No. 1575676.(No model.)

To cpi/,ZZ whom it may concern:

Be it known that I, ELwooD SCOTT, a citizen of the United States,residing in the city of Marion, in the county of Grant and State ofIndiana, have invented certain new and useful Improvements in RadiantStoves, of which the following is a specification, which, taken inconnection with the accompanying drawings, forming a part thereof, issufficiently clear and concise as to enable others skilled in the art towhich it appertains to make and use the same.

My present invention does not contemplate a radical departure from theprinciples heretofore involved in devices of this character, but ratherthe adaptation of well-known principles with their mechanical elementsreduced to their simplest proposition and asa natural sequenceaccentuating the utilitarian resid'- ual benefits thereof and adaptingthem yto subserve the highest economic ends.

The objectof my present invention,broadly speaking, is to provide astove composed of cooperating, interdependent, and subsidiary elementsarranged and combined to subserve the highest economic ends.

Another object is to provide a stove coutaining a great amount ofheating-surface adapted to accentuate and utilize the otherwise wasteheat produced therein in order that it may be used for raising thetemperature in a building with a minimum of fuel and a resultantdecrease of the labor of maintenance thereof.

Another object is to provide a stove composed of sections vof metal soarranged and combined that the maximum amount of heat may be obtainedfrom a minimum of fuel therein and so evenly distributed that all partsof the stove will be heated equipollently and in a minimum of time. I

Another object is the provision of an article of manufacture, a stovecomposed of a4 minimum of component mechanical constituent elements toproduce Vcommensurate vresults, easily operated and maintained, simplein character, compact in form and construction, and which can bemanufactured and sold at a comparatively low price. v

The particular object of my invention is the provision of a stove usingas a fuel natural or artificial gas, oil, vapor, wood, coals coke, orother material, to be consumed therein in any preferred manner andadapted to obtain from the results of the combustion the full maximumamount of the heat generated thereby and to radiate it to the room orapartments to be warmed thereby.

Other objects and advantages of my invention will appear from thedrawings and from the following specification and correlated in theclaims hereunto appended.,

This invention relates to that class of radiators in which a greatamount of heating or radiating surface is provided with a minimum amountof space occupied by the stove.

My invention consists in a radiant stove embodying new and usefulfeatures of construction and relative disposition of the several parts,`substantially as particularly described otherwhere in this specificationand in the legitimate combinations herein set forth.

One manner of carrying out the objects of my invention and that which inpractice is found the most desirable is illustrated in the accompanyingdrawings, in which- Figure l shows a vertical longitudinal section of myinvention. Fig. 2 shows a rear elevation of same, partly in section, inorder to showthe interior of a portion of the radiator-Iiues. Fig. 3 isa horizontal cross-section of my invention, taken on the lines X X ofFigs. 1 and 2. Fig. at is a horizontal crosssection of my invention,taken on the lines Y Y of Figs. l and 2; and Fig. 5 is a horizontalcross-section of my invention, taken on the lines Z Z of Figs. 1 and 2.

Similar characters refer to and denote like parts throughout the severalviews, and the arrows denote the course of the various drafts.

For a more thorough understanding and comprehension of my invention Iwill now proceed to take up the description thereof. in detail, which Iwill refer to as briefly and oompactly as I may.

In the drawings the letter A represents the combustion-chamber of mystove, with a res ervoir B leading thereto from the` top.

Y C represents the floor-line. y

D is a removable top, and E the smoke and IOO foul-air exit. Said partsmay be variously changed and may be of any preferred construction inorder to meet various conditions. It will be observed that theconstruction of my stove contemplates acombination of stove andradiator, the latter part being located in this instance in the rear andthe former in the front, as shown in the drawings, with means for thepassage of the heated air therebetween through Various channels,or therelative locationvof the stove and radiator portions may be variouslychanged to meet the requirements of various kinds of fuel which may beused or for specific purposes. Back of the front portion of my stove Iarrange a plurality of comparatively flat oblong ues, (represented bythe numeral 1,) arranged in a lier near-each other and extending fromnear the fuel-chamber to back of the stove. Each of said flues opensinto a chamber located below their lower ends and the bottom of thestove, and the upper ends of each alternate flue open into an upperchamber 3, and the alternate tlues open into an upper front chamber. Inthe partition dividing the chambers 3 and 4 is a damper 5, operativefrom the outside of the stove by a handle 6. In the partition dividingthe chamber 4 from the upper part of the fuel-chamber isa damper 7,operative from the outside of the stove bya handle 8. In front of thechamber 2 below the fuel-cham ber is a chamber G, with a passagewaytherefrom leading into thechamber 2, saidpassages being adapted to beopened and closed by the double dampers H and H,which 'latter aresecured toa shaft common to both and operative by the handle I from theoutside of the stove. Rising from the rear upper corner of the chamber Gis a partition 9,which extends up only a slight distance above the mouthof the reservoir B, as indicated in the drawings. A slight distance inthe rear of the partition 9.is a partition 10, which extends from thetop of the stove downward to the bottom of the stove, forming the backof the stove proper. The damper 7 is adapted to close a passage formedthrough the partition l0, at the upper end thereof above the flues 1,which passage leads from the upper portion of the fuel-chamber to thechamber 4. Extending forward from the inner wall of each of the openingsclosed by the dampers H and H are partitions J and K in the chamber G,as shown in Fig. 5. It will be apparent by reference to Fig. 3 thatone-half of the upper end of each of the ilues l is closed, the openingin the upper end of the dues being alternately in the front and rear inorder that each alternate fine will open into the chambers 2 and 4. Itwill also be noticed that there is an open space between each of theiiues; between the inner edges of the fines and the partition 10;through the bottom of the stove in the front of the lines, leading intothe space between the dues and the partition lO, and `from thelast-named space around the passage Y closed by the damper 7 tounderneath the top D, from which latter space the heated air may passthrough the openings L in said top D, and all of which open spaces theair may freely circulate and by means of which the radiating capacity ofmy stove may be greatly increased.

From the above-described construction it will be apparent that should are be maintained in the fuel-chamber that the stove may be operated in avariety of ways. For instance, the dampers 5 and 7 may be turned back oropened andthe dampers H and'H closed, which will allow the heat to passdirectly from the fuel-chamber through the chambers 3 and 4 to the exitE, thus giving a direct draft, or by opening the dampers H and H andrclosing the damper 7 the heat will pass down between the partitions 9and 10 into the chamber G, over the dampers H and H into the chamber 2,then up the flues 1 into the chambers 3 and 4, and then through to theexit E, and by closing the dampers H and H, opening the damper 7, andclosing the damper 5 the heat will pass from the fuelchamber into thechamber 4, down each alternate flue 1 into the chamber 2, up eachalternate line into the chamber 3, and then out through the exit E. Bythus manipulating the dampers it will be apparent that the heat will bebrought into contact with a great amount of radiating-surface withoutmaterially decreasing the draft of the stove. It will also be apparentthat the flues 1 being formed, preferably, of sheet metal or the likewith their sides close together that thereby very narrow channels areformed, through which the heat must pass, and consequently all of theheat is brought very near to the surface-that is to say, near to the airsurrounding the stove-and therefore the radiation of the heat will bevery rapid, and I have also demonstrated that by the time the heat fromthe lower chambers has reached the exit that practically all of the heatwill have been radiated therefrom and transmitted tov the room in whichthe stove is located.

It will be noticed that my stove will be comparatively light in weightand will occupy a very small compass of space, while at the same timewill contain a great amount of radiating-surface.

My invention is perfectly adapted to accomplish the results for which itis intended, and it is evident that changes in and modications of thespecific .construction herein shown and described may be made and thatanalogous parts may be used to accomplish the same results withoutdeparting from the spirit of my invention or sacrificing any of its manyadvantages, and the specific construction of the details of myinvention, in which novel features are embodied, may be variouslychanged without altering the essential principles which are claimed asnew.

Having now fully shown and described my IOO IIO

invention and the best manner for its construction to me known at thistime, what I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. In a stove the combination of a series ofv flat lilies arrangedparallel and near each other, each of said iiues extending from near thetop to near the bottom of the stove in the rear of the fuel-chamber, achamber in the base into which said fines open, a rear and a frontchamber above the lines, each alternate flue opening into said front andrear chamber, and the dampers for controlling the route the heat shallfollow in its outward course, all substantially as shown and described.

In a stove the combination of a series of flat lues arranged paralleland in alinement with each other in the rear of the fuel-'chamber, abase -chamber into which all of said ilues open, an upper front chamberinto which each alternate fl ue opens, an upper rear chamber into whicheach alternate ilue opens, a-

passage between the upper front and rear chambers, a passage between theupper front chamber and the upper portion of the fuelchamber, a passagebetween the fuel-chamber and the said base-chamber, and dampers foropening and closing each of said passages, all substantially as shownand described.

3. In a stove the combination of a series of flat ues arranged paralleland near each other, each of said Ilues extending from near the top tonear the bottom of the stove in the rear of the fuel-cham ber, a channelbetween the fuel-chamber and the lues, a chamber in the base into whichall of said llues open, a rear and a front chamber above the dues, eachalternate liuc opening into said front and rear chamber, and a series ofdampers for determining the route the heat shall fol- `low in itsoutward course, all substantially as shown and described.

et. In a stove the combination of a series of flat lines arrangedparallel and near each other, each of said ues extending from near thetop to near the bottom of the stove, a chamber in the base into whichall of said flues open, a two-part chamber above the lines into whichthe {iues open alternatively, a channel extending from the fuel-chamberto the base-chamber controlled by a damper, a passage from thefuel-chamber .through the upper chamber tothe exit controlled bydampers, and means for controlling thecourse of the heat by theoperation of said dampers, substantially as shown and described.

5. In a radiant stove, the combination with a fuel-chamber and an exit,a series of flat ues arranged vertical and parallel between .saidfuel-chamber and exit, a chamber in the base into which all of saidilues open, a passage from the fuel-chamber to said base-cha mber,

.a damper for controlling said passage, an up-v -for the purposes setforth.
